    1420== The Testbed ==
    15 Sandbox 9 consists of three nodes connected to the SB9 Console through a !OpenFlow enabled switch. The !OpenFlow enabled NEC IP8800/S3640-48T2XW switch currently runs firmware supporting !OpenFlow v0.8.9. The switch is pre-configured so that ports 25-36 (the data VLAN, in green) is an !OpenFlow virtual switch that listens for a controller running on the SB9 Console. The network topology is shown below:

     26The blue switch (sw_sb09) represents the !OpenFlow enabled NEC IP8800/S3640-48T2XW switch, currently running firmware supporting !OpenFlow v0.8.9. The switch is pre-configured so that ports 25-36 (the data VLAN, in red) is an !OpenFlow virtual switch that listens for a controller running on the SB9 Console. Two trunked connections exist - one connects the setup with the ORBIT network (through sw_sb_top), and  the other not only allows the console to communicate with the nodes, but also provides the secure controller-switch VLAN needed for the !OpenFlow setup. The experimenter would be able to monitor and manipulate the setup from the Console.
